Any changes planned for DKs? Like removing the rp cost from Icebound Fortitude or removing the health loss every 2 sec from Unholy Frenzy.

As you can see, the question is not about the planned changes for patch 5.3. For those that are complaining that you aren't satisfied with the questions we responded to, take into consideration the following things:

Did you ask a question? We only took questions that were posted in the Ask the Devs thread. If you don't ask, we can't answer.

Was your question about the patch 5.3 changes relating to PvP? If not, then it was not taken because it broke one of the first rules for the Ask the Devs

Did you up-vote questions you wanted to see answered? The highest voted questions were the ones we chose.

There were many questions that were able to be asked about the 5.3 changes for PvP. There was a new battleground, a new arena, many class changes that would affect PvP and as can be seen, resilience changes. No questions were avoided, if they met the rules of the thread and were voted for, then they were chosen.

The major things which are constanly posted about here and on the usa forums: too much burst, too much cc +remove the pve trinkets, are simply ignored.

There are actually responses to all three of those. The Devs spoke about CC, the PvE trinkets and the burst they create. Unfortunately, if you check the Ask the Devs thread, there are no questions which actually asked about the 5.3 changes and the way in which they would address burst, outside of those pertaining to the Shado-Pan trinkets. If you wanted an answer specifically to the ways in which 5.3 was planning to address your particular issues with burst, then you should have asked them.
